.csv file properties via SQL

Is it possible to access file properties such as the modified date via sql?
We have an export from one system that is stored in a .csv format and is updated on an iregular schedule. I can access and import the data into a table, but would like to avoid that overhead if possible. Seems the easiest way would be if I could access the modified date, store it in the db, and only import the data if the date has changed.
